The cost-of-living index, also known as the Consumer Price Index (CPI), is a measure of the average change in prices of goods and services that households consume. It is used to compare the cost of living between major cities or regions. There are several synonyms for the cost-of-living index, including the inflation rate, purchasing power index (PPI), and consumer price index for urban wage earners and clerical workers (CPI-W). The inflation rate measures the increase in prices of goods and services over a certain period, while the PPI gauges the relative prices of goods and services in different locations. The CPI-W is a more specific version of the CPI, focusing on households with urban wage earners and clerical workers.
